What are some potential problems with using a canary instead of an electric alarm?

Using a canary as an early warning system for toxic gases can be problematic due to its biological limitations; the bird may not react quickly enough or may become ill before the danger is detected. Additionally, canaries are sensitive to a limited range of gases and may not provide comprehensive coverage for all potential hazards. There are also ethical concerns regarding the welfare of the animal, as well as the logistical challenges of keeping and monitoring a living creature in hazardous environments. In contrast, electric alarms are reliable, continuous, and can detect a broader range of threats without compromising the welfare of any living beings.
